How Do I Keep My CSA Veggies Fresh on the Way Home?

Q: I recently signed up for my first CSA, which I pick up after work then travel with for a 2-hour commute. The organization requires that we bring our own bags and no matter what I pack the veggies in, half end up wilted, brown, or squashed (hehehe..."squash"). How do I get my produce home safely?

Editor: Are you able to bring a cooler with cold packs? I realize that might not work if your commute involves public transportation, but if you're driving, that might work!
